    Abstract: A device (10) operable in a ultra-high vacuum and in a cryogenic environment. The device has bi-stable solenoid motors (18) configured to drive a shutter assembly (12) defining an aperture (15) having a first shape when the motors are each disposed in the respective first position, and wherein the aperture has a second shape when the motors are each disposed in the respective second position. Actuators (30) responsive to the motors are thermally isolated from the cryogenic shutter assembly except when the motors position the shutter assembly to change a shape of the aperture. The device is suitable for use in FLIR and other thermally sensitive devices.

    Abstract: A shutter assembly (12) comprising a first planar member (70) and a second planar member (72) opposed from one another and forming a sleeve having a cavity (80) therebetween, the sleeve having a pair of side rails (78) adjacent the cavity along sides of the sleeve. A first shutter member (14) having a first end (92) is disposed in the cavity and slidingly disposed along one of the side rails, and a second shutter member (14) having a second end (92) is disposed in the cavity and slidingly disposed along the other side rail. The first end is opposed to the second end and is configured to be selectively advanced towards, and retracted from, the second end so as to define an aperture (15) therebetween having a first shape when disposed in a first position, and wherein the aperture has a second larger shape when the first end is disposed in a second position. The first shutter member and the second shutter member maintain a thermal contact with the side rails and the planar members in all positions. The shutter assembly is well suited to be used at a cryogenic temperature and in a high vacuum environment.
